In the phase 3, randomized, double-blind RIsperidone Subcutaneous Extended-release (RISE) study, TV-46000 once monthly (q1m) and once every 2 months (q2m) significantly prolonged time to impending relapse compared with placebo [5.0-fold (q1m) and 2.7-fold (q2m)]. This phase 3, randomized, double-blind Safety in Humans of TV-46000 subcutaneous INjection Evaluation (SHINE) study was designed to evaluate the long-term safety, tolerability, and exposure of TV-46000 in schizophrenia.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Patients who completed RISE without relapse (rollover) or who were newly recruited (de novo) were eligible for the SHINE study. Patients were initially stabilized on oral risperidone for 12 weeks (completed in RISE for rollover, or in SHINE for de novo). Patients in the de novo cohort and patients who received placebo in RISE were randomized 1:1 in SHINE to receive TV-46000 q1m or q2m for up to 56 weeks. Primary endpoint for SHINE was frequency of reported adverse events (AEs); event rates [ER; events per 100 patient-years (PYs)] were calculated for each AE by patients upon general questioning.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Overall, 336 patients were randomized in SHINE [TV-46000 q1m, n = 174; TV-46000 q2m, n = 162; of these, de novo, n = 109 and rollover, n = 227 (n = 172 patients were treated and n = 55 received placebo)]. A total of 334 patients were evaluated for safety [q1m, n = 172 (PY = 97.8); q2m, n = 162 (PY = 104.5)]. Proportions of patients (ER) with ≥ 1 AE and ≥ 1 treatment-related AE were 37% (180.0) and 21% (84.9) for TV-46000 q1m and 46% (157.9) and 20% (70.8) for TV-46000 q2m, respectively. Frequent treatment-related AEs [≥ 3% of patients in either group; proportion of patients (ER)] were injection site pain [q1m, 5% (24.5); q2m, 4% (22.0)] and injection site nodule [q1m, 2% (9.2); q2m, 6% (12.4)]. The proportions of patients with serious AEs was 5% for TV-46000 q1m and 7% for TV-46000 q2m; serious AEs reported for ≥ 2 patients overall were worsening schizophrenia [q1m, n = 1 (&lt; 1%; ER, 1.02); q2m, n = 2 (1%; ER, 1.91)] and hyperglycemia [q1m, n = 1 (&lt; 1%; ER, 1.02); q2m, n = 1 (&lt; 1%; ER, 0.96)].

Combination therapies may address core features, non-specific co-pathology commonly occurring in patients with AD (e.g., inflammation), or non-AD pathologies that may co-occur with AD (e.g., α-synuclein). Combination therapies may be advanced through co-development of more than one new molecular entity or through add-on strategies including an approved agent plus a new molecular entity. Addressing add-on combination therapy is currently urgent since patients on anti-amyloid monoclonal antibodies may be included in clinical trials for experimental agents. Phase 1 information must be generated for each agent in combination drug development. Phase 2 and Phase 3 of add-on therapies may contrast the new molecular entity, the approved agent as standard of care, and the combination. More complex development programs including standard or modified combinatorial designs are required for co-development of two or more new molecular entities. Biomarkers are markedly affected by anti-amyloid monoclonal antibodies, and these effects must be anticipated in add-on trials.

Despite increasing understanding of migraine neurobiology and the impacts of this on therapeutic developments, there remains a need for treatment options for patients underserved by currently available therapies. The first specific drugs developed to treat migraine acutely, the serotonin-5-hydroxytryptamine [5-HT_1B/1D] receptor agonists (triptans), seem to require headache onset in order to have an effect, while early treatment during mild pain before headache escalation improves short-term and long-term outcomes. Some patients find treating in the early window once headache has started but not escalated difficult, and migraine can arise from sleep or in the early hours of the morning, making prompt treatment after pain onset challenging. Triptans may be deemed unsuitable for use in patients with vascular disease and in those of older age and may not be effective in a proportion of patients. Headache is also increasingly recognised as being just one of the many facets of the migraine attack, and for some patients it is not the most disabling symptom. In many patients, painless symptoms can start prior to headache onset and can reliably warn of impending headache. There is, therefore, a need to identify therapeutic targets and agents that may be used as early as possible in the course of the attack, to prevent headache onset before it starts, and to reduce both headache and non-headache related attack burden. Early small studies using domperidone, naratriptan and dihydroergotamine have suggested that this approach could be useful; these studies were methodologically less rigorous than modern day treatment studies, of small sample size, and have not since been replicated. The emergence of novel targeted migraine treatments more recently, specifically calcitonin gene-related peptide (CGRP) receptor antagonists (gepants), has reignited interest in this strategy, with encouraging results.
